Key Features of the RockJam KB100 Keyboard Bench
1. Sturdy X-Style Design
The RockJam KB100 has an X-style frame made of steel, which gives it a sturdy and reliable foundation. This classic design ensures stability and adds an extra layer of durability. Despite its affordable price, the build quality of the KB100 provides a level of strength that should satisfy most casual players.
The frame is reinforced to support up to 100 kg (220 lbs), which means it is suitable for a wide variety of body types. This makes it an attractive option for players of different ages, whether they are children learning to play the piano or adults needing a comfortable, stable seat.
2. Height Adjustability
The bench offers three adjustable height settings, ranging from 17 to 20 inches. This makes it versatile enough to accommodate players of different heights and allows it to work well with various types of keyboards or digital pianos. The adjustable height settings make the bench adaptable for different playing environments and styles, whether you’re performing at a table-height keyboard or practicing on a digital piano at home.
3. Thick Padding for Comfort
The seat cushion of the RockJam KB100 is 2.75 inches thick and made of high-density foam. The padding is covered with a black vinyl material that looks sleek and is easy to clean. The cushion is designed to provide comfort during longer practice sessions, which is especially important for musicians who spend hours perfecting their craft.
While it may not offer the plush luxury of a premium bench, it certainly provides more than adequate support for the majority of players, allowing you to stay comfortable for a good amount of time without feeling fatigued.
4. Portability and Storage
The KB100’s folding X-frame makes it highly portable and easy to store. Whether you’re a musician who travels between different practice spaces or someone who needs to store their bench in a small apartment, this bench’s ability to fold flat is a major advantage. It’s also relatively lightweight at around 4.2 kg (approximately 9 lbs), making it easy to carry.
5. Non-Slip Rubber Feet
The bench is equipped with non-slip rubber feet, providing excellent stability on different types of flooring. These rubberized ends help keep the bench from slipping around while you’re playing, giving you extra confidence and allowing you to stay focused on your music rather than worrying about a wobbly seat.

Pros of the RockJam KB100 Adjustable Keyboard Bench
1. Affordability
The RockJam KB100’s biggest selling point is its affordability. Priced significantly lower than many other adjustable keyboard benches on the market, the KB100 offers excellent value for money. If you’re a beginner or intermediate player on a budget, this bench provides all the essential features you need without breaking the bank. The Yamaha PKBB1 is another option, if you’ve a little more to spend on your purchase.
2. Easy to Set Up and Use
The X-style folding frame makes setup incredibly easy. You can unfold and secure the bench in just a few seconds, which is ideal for those who don’t want the hassle of complicated assembly. The simple design and straightforward adjustment mechanism mean that even those with no experience in setting up musical gear can do it with ease.
3. Sturdy Construction
Despite being budget-friendly, the RockJam KB100 boasts a solid steel frame that can support a considerable amount of weight—up to 100 kg (220 lbs). This sturdy construction gives the bench a stable feel, and you won’t experience wobbling or instability, even when sitting for extended periods.
4. Adjustable Height
The three adjustable height settings (ranging from 17 to 20 inches) make the RockJam KB100 suitable for different types of keyboards and players. Whether you’re a young musician or an adult, you’ll be able to find a comfortable height to suit your playing position. This flexibility is a major advantage over fixed-height benches, which may not always match your instrument’s height or your posture requirements.
5. Portable and Space-Saving
The lightweight and foldable design makes this bench highly portable and convenient to store. If you need a bench that can easily be packed away after use or one that can accompany you to lessons or gigs, the KB100 is a great choice. Its compact size also makes it ideal for players who need to conserve space.
6. Comfortable Padding
The 2.75-inch thick cushion provides a reasonable amount of comfort, even during longer sessions. The padding is firm enough to offer good support without being too stiff, making it a good choice for beginner and intermediate players. While high-end benches may provide extra plushness, the KB100 certainly does a commendable job of keeping you comfortable during average practice times.
Cons of the RockJam KB100 Adjustable Keyboard Bench
1. Limited Height Adjustment
While the RockJam KB100 does have three adjustable height settings, the range of adjustments is somewhat limited compared to more premium models. The difference between the lowest and highest settings is just 3 inches (17 to 20 inches). This might not be enough for everyone, particularly those with specific posture needs or who play at unusual keyboard heights.
2. Not Ideal for Extended Practice Sessions
The bench’s padding, while decent, may not be ideal for very long practice sessions. The cushion is relatively firm, and over time, some users may find it lacking the plushness needed for prolonged comfort, especially if they tend to spend hours seated at their instrument. If you frequently engage in extended practice sessions, you might want to look for a bench with thicker or more ergonomic padding.
3. Basic Aesthetic Design
The aesthetic design of the KB100 is quite basic, which may not appeal to players who prefer something more visually sophisticated. It has a utilitarian look, typical of entry-level benches, and may not match the appearance of classic or more expensive keyboards. For those who are particular about how their equipment looks in their home or studio, the minimalist design of the RockJam KB100 might not be the most appealing.
4. Weight Limit
The KB100 has a weight capacity of 100 kg (220 lbs). While this will be suitable for most players, heavier individuals may need to consider other benches with a higher weight capacity to ensure a stable and comfortable experience. Heavier players may also find that the bench feels less stable if they are approaching the weight limit.
5. No Ergonomic Features
The RockJam KB100 is a simple bench, and as such, it lacks any specific ergonomic features like lumbar support, seat contouring, or a backrest. These features are often found in more premium benches and can make a big difference for players concerned about maintaining proper posture during long hours of practice. If ergonomics are important to you, you may need to invest in a higher-end model.
